Publication number: 20140017431Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.Type: ApplicationFiled: September 9, 2013Publication date: January 16, 2014Applicant: M & G USA CORPORATIONInventors: Edwin Andrew Sisson, Arianna Giovannini, Simone Ferrero

Publication number: 20130072603Abstract: The present invention is to a composition made from a polyester produced by the acid or ester polyester process, a cobalt salt and a base, preferably an alkaline metal base. The composition can be made by blending a cobalt salt with a polyester which has been polymerized in the presence a alkaline metal ion derived from a basic alkaline metal compound, e.g. alkaline metal base or basic alkaline metal salt. The composition may optionally comprise an ionic compatibilizer, which may further be blended with a partially aromatic polyamide. This blend can be processed into a container having both active and passive oxygen barrier with an improved color and clarity than that achieved by cobalt alone. The use of the cobalt salt in combination with the base can also be used to improve the color of recycled polyester durin processing.Type: ApplicationFiled: November 15, 2012Publication date: March 21, 2013Applicant: M&G USA CORPORATIONInventor: M&G USA CORPORATION

Patent number: 8231937Abstract: Compartmentalized chips of at least two chemically similar crystallizable thermoplastic polymers each having a different intrinsic viscosity placed in separate zones are disclosed. These compartmentalized chips exhibit thermal characteristics that are different from the traditional technique of homogeneously combining the two materials into the chip. These compartmentalized chips in their amorphous, crystalline and solid phase polymerized forms exhibit a longer crystallization half time than the homogeneous mixture, thus permitting faster injection cycle times when compared to an equivalent homogenous mixture.Type: GrantFiled: July 8, 2011Date of Patent: July 31, 2012Assignee: M&G USA CorporationInventors: Delane Nagel Richardson, Edwin A. Sisson, Gianluca Ferrari, Dan Gastaldo, Freddie L. Massey
